Note that all 154X B's are known to work, while some very old A's are
reported to cause troubles.  Mine works however, and i know of at
least one more 1542A that does also work fine under FreeBSD.  For
large transfers, the performance isn't worse than that of a 1542B.

The 154X driver in FreeBSD is probably one of the most solid SCSI
drivers around in the system.

Never trust an operating system you don't have sources for. ;-)
